What is the purpose of escape ramps?

Escape ramps are specifically designed to provide a means of stopping for vehicles that are experiencing brake failure or that are otherwise unable to slow down effectively while traveling downhill. These ramps are built with a steep incline or a surface designed to help slow down a vehicle quickly through friction or an elevated, sandy, or gravel bed. This safety feature is especially important in mountainous or hilly areas where heavy vehicles, such as trucks, may descend at high speeds and face the risk of losing braking power. By utilizing these escape ramps, drivers can safely bring their vehicles to a stop, thereby preventing potential accidents or collisions that could result from runaway vehicles.

While other options may address different aspects of roadway safety or traffic management, escape ramps serve a crucial role in ensuring that drivers of heavy-duty vehicles have a way to regain control and avoid catastrophic consequences in the event of brake failure.
